IMPROVEMENT IN sAsH-FAsTENERs.

Specification forming part of Letters Patent No. 177, l l0, dated May 9,1876; application led February 2l, 1876.

To all whom 'it may concern:

Be it known that I, EDWIN H. FENToN, of New Haven, in the county of NewHaven and State of Connecticut, have invented a new Improvement inSash-Lock; and I do hereby declare the following, when taken inconnection with the accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part ot' this specification, andrepresent, in-

Figure l, a front View; Fig.`2, a side View; Fig. 3, the reverse side,and'in Figs. 4 and 5 transverse sections.

This invention relates to an improvement in device for lockingwindow-sashes, the obv ject being to construct a lock which may bearranged so as to appear as a part of the parting-s trip between thesashes; and it consists in a turn-button arranged with a tongue at oneend, which, as the button is turned, will pass into a correspondingnotch in the upper' sash, when the outer end will move out over andclose upon the top ofthe lower sash, combined with a locking device toretain said button in its locking position.

A is the base or plate on which the button Bis pivoted. This button ismade to conform substantially to the parting-strip C in the frame, theplate Abeing set flush with the stile D. The button is constructed witha tongue, E, which, when the button is turned into its vertical orunlocking position, as indicated in Fig. l, lies within the width ot'the parting-strip C; but, when turned, as seen in Fig. l, the tongue Eprotrudes beyond the parting-strip upon one side, while the heel Fprotrudes upon the opposite side. The tongue passes into a notch in theupper sash, and` the heel over and in close proximity to the meetingrail of the lower sash; hence, when turned into this position, the heelF prevents the raising of the lower sash, while the tongue E preventsthe movement of the upper sash.

,'In order to lock the button so that it cannot be tampered with fromthe outside, a bolt, a, is arranged in the heel of the button, whichextends down through a slot, b, in the plate. The bolt is formed with agroove, d, and the slot b is made to correspond to the said groove, butwith an enlargement, as indicated in Fig. 1, so that the'lower end ofthe bolt may rise into the enlarged portion. The bolt is provided with aspring, e, the tendency of which is to throw it outward; hence, when thebutton is turnedto the locking position, the bolt will be thrownoutward, so that the lower end will pass into the enlarged portion ot'the slot b, as indicated in Figs. 2, 3, and 5; but when the bolt ispressed inward, as seen in Fig. 4, then the groove in the bolt willallow the button to be turned into the unlocked-position, and the boltwill be held in by the contracted part of the slot b, as seen in Fig. 4.

Additional security may be made by application ot' a similar bolt, f,the spring h of which will fall into the groove in the bolt when it israised, as indicated in Figs. 3 and 5, so that before the bolt can bedepressed i'or unlocking the bolt f must also be depressed to releasethat bolt.

rlhe locking device may be modified or l changed without tion.

I elaimy A turn-button, B, having the tongue E, adapted to lit in andappear as a portion ot the parti'ngstrip, and pivoted, as described, toengage both the upper and lower sash, combined with a suitable springand locking device, substantially as speciiied.
